Error loading mdata-worker

[dcinzona]

I pulled down the repo and kicked it off via the shell script.
NPM modules install (with some vulnerabilities) and I get an error stating Error: Cannot find module 'antlr4/index

The web UI starts up fine, and when I go to log into my org, the callback errors out stating it received an empty payload:
Empty payload received. Try again !!!
